- Flexible flat cables can be integrally welded to a circuit board for making a connection between the flexible flat cable and the circuit board, therefore the reliability of the weld directly affects the connection of the flexible flat cable and the circuit board. A testing process is needed before the assembly of the flexible flat cable and the circuit board is sold. In the testing process, the flexible flat cable and the circuit board are pulled away from each other, and a pulling force is generated.

Thecontrol system 11 receives the fluctuating current, calculates the value of the pulling force according the fluctuating current, and displays the value of the pulling force via thedisplay panel 116. -
FIG. 5 shows that thematerial clamping mechanism 18 includes apositioning device 181 attached to thetest platform 106 and aclamp 188 attached to thepositioning device 181. Thepositioning device 181 is configured to adjust the location of theclamp 188, thus making theclamp 188 align with theload sensor mechanism 15. Theclamp 188 is configured to clasp the test object. - The
positioning device 181 includes afirst position plate 182, asecond position plate 184 and aclamp platform 186. Thefirst position plate 182 is fixed to thetest platform 106 and includes afirst rail 183 extending along a second direction perpendicular to the first direction, and the second direction is a direction parallel to an X-axis as shown inFIG. 5 . Thesecond position plate 184 slidably attaches to thefirst position plate 182 and is configured to move back and forth along thefirst rail 183. Thesecond position plate 184 includes asecond rail 185 extending along a third direction perpendicular to the first and second direction, and the third direction is a direction parallel to a Y-axis as shown inFIG. 5 . Theclamp platform 186 slidably attaches to thesecond position plate 184 and is configured to move back and forth along thesecond rail 185. Theclamp 188 is fixed to theclamp platform 186. - The
clamp 188 includes amain body 1880, apressing body 1883, afixing rod 1881, anelastic member 1882, and afixing bolt 1884.

Eachvertical plate 1885 defines a throughhole 189. The fixingrod 1881 extends perpendicularly to thevertical plates 1885. - The
pressing body 1883 is located between the twovertical plates 1885 and defines a throughhole 189 extending perpendicular to thevertical plate 1885. The fixingrod 1881 passes through the throughholes 189 of thevertical plates 1885 and thepressing body 1883 and rotatably fixes thepressing body 1883 to themain body 1880. Thepressing body 1883 serves as a seesaw. Thepressing body 1883 includes a first side and a second side opposite to the first side. Apressing nozzle 1887 is attached to thepressing body 1883 at the second side, and thepressing nozzle 1887 defines a notch. The fixingbolt 1884 passes through thepressing body 1883 at the first side by screwing and is further screwed in thefixing plate 1888. Theelastic member 1882 is arranged between thepressing body 1883 and thefixing plate 1888 on the second side, and applies a resilient force to thepressing body 1883 when thepressing body 1883 is moved. When thefixing bolt 1884 rotates, the fixingbolt 1884 drives the first side of thepressing body 1883 to move upward or move downward along the first direction, thus driving thepressing nozzle 1887 to move closer to thefixing plate 1888 or move further away from the fixingplate 1888. When thepressing nozzle 1887 moves closer to thefixing plate 1888, theclamp 188 is at a clasped state (seeFIG. 7 ), the first element of the test object can be clasped by thepressing nozzle 1887, and the second element of the test object can extend out of thepressing nozzle 1887 via the notch of thepressing nozzle 1887.

testing device 1 is used, the tester rotates thefixing bolt 1884, opening theclamp 188. The first element of the test object is inserted between thepressing body 1883 and thefixing plate 1888. The welded portion of the test object corresponds to the notch of thepressing nozzle 1887, and the second element of the test object extends out of thepressing nozzle 1887 via the notch and positions above thepressing nozzle 1887. Then the fixingbolt 1884 is rotated to clasp theclamp 188, the first element of the test object is firmly pressed below thepressing nozzle 1887, therefore thepressing nozzle 1887 clasps the first element of the test object. The location of theclamp 188 is adjusted by sliding thesecond position plate 184 and theclamp platform 186, thus making the welded portion of the test object align with theclasp mechanism 156 of theload sensor mechanism 15. The second element of the test object is clasped by theclasp mechanism 156. - When the first and second elements of the test object are clasped by the
clamp 188 and theclasp mechanism 156, the tester inputs operation signals viacontrol buttons 110 to rotate theservo motor 131, rotating thetorque controller 132 and thescrew rod 134, and thus moving the slidingblock 136 upward and downward along the first direction. Theload sensor mechanism 15 moves further away in unison with the slidingblock 136 from theclamp 188 or moves closer to theclamp 188. When theload sensor mechanism 15 moves further away from theclamp 188, the pulling force along the first direction is generated at the welded portion of the test object. Thetesting device 1 detects the pulling force and outputs the value of the pulling force via thedisplay panel 116. The pulling force is gradually increased when theload sensor mechanism 15 moves further away from theclamp 188. When the pulling force of the test object equal to a predetermined pulling force, the tester inputs operation signals to stop the rotation of theservo motor 131, and determine the reliability of the weld by whether the welded portion of the test object is able to endure the predetermined pulling force. - The
testing device 1 has a measurement range, when the pulling force is greater than the maximum of the measurement range, thetorque controller 132 rotates and stops to drive thescrew rod 134 to rotate. -
FIG. 8 shows a flowchart summarizing a method for testing the pulling force of the test object according to an exemplary embodiment of the present disclosure. The testing steps are described below. - In step S10, the first element and the second element of the test object are clasped by the load sensor mechanism and the clamp, respectively.
- In step S11, the
clamp 188 is adjusted to align with theload sensor mechanism 15. - In step S12, operation controls is inputted into the
control system 11 viacontrol buttons 110 to drive theload sensor mechanism 15 to move upward along the first direction, theload sensor mechanism 15 and theclamp 188 moved further away from each other, the pulling force perpendicular to thetest platform 106 generated between the two portions of the test object. - In step S13, the pulling force is detected by the
load sensor mechanism 15 and the detection is fed back to thecontrol system 11. - In step S14, the tester can receive the detection via the control system and determine the reliability of the weld.
- With the above-described configuration, the tester can use the
testing device 1 to detect the pulling force of the test object, the user only needs to input operation signals via thecontrol buttons 110, and the testing result is consistently precise. - The
testing device 1 is not limited to the above-described configuration, the positioning device only has only one position plate, the first rail is arranged on the test platform, and the second rail is arranged on only one position plate. - It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages, the examples hereinbefore described merely being exemplary embodiments.
